  1. How many com ports do you have? older computers have 1 or 2. new computers dont have any at all. try the device on com1 and if it doesnt work, either swap the cable on the back of the computer or try com2.
  2. Are you trying to hang a device from an existing port or just find what port an existing device is using?
